तस्मादृचः साम यजूꣳषि दीक्षा
यज्ञाश्च सर्वे क्रतवो दक्षिणाश्च ।
संवत्सरश्च यजमानश्च लोकाः
सोमो यत्र पवते यत्र सूर्यः ॥ ६॥

tasmādṛcaḥ sāma yajūꣳṣi dīkṣā
yajñāśca sarve kratavo dakṣiṇāśca ।
saṃvatsaraśca yajamānaśca lokāḥ
somo yatra pavate yatra sūryaḥ ॥ 6॥

From Him are the hymns of the Rig Veda, the Sama and the Yajur, initiation, and all sacrifices and works of sacrifice, and dues given, the year and the giver of the sacrifice and the worlds, on which the moon shines and the sun.
